Distillation section for coal-based ethylene glycol

Thread Content

The composition of the material entering the tower is as follows: DMO: 32.53 kmol/h; EG: 587.06 kmol/h. The separation accuracy for DMO is 0.98, while that for EG is 0.99. EG exits from the bottom of the tower. I would like to know what the minimum and optimal reflux ratios should be How to calculate it?

The current main process for producing ethylene glycol from coal is the “indirect method”, which involves generating syngas through coal gasification, catalytically coupling CO to form oxalate esters, and then hydrogenating them to produce ethylene glycol.

There is a formula for this reflux ratio. . .
